Artemis is building the future of AI-driven defense - helping companies detect and defend themselves effectively in an era where AI is fighting AI on the cyber battlefield. As an AI-native Protection Platform, Artemis reliably detects and contains important threats with actionable context. By streaming only detection-critical logs and retrieving the rest on demand in a federated manner, it reduces cost while ensuring full visibility. Because it agentically and continuously adapts to changes in your environment and the threat intelligence landscape, your detection coverage never falls behind - delivering stronger protection. We’re backed by Felicis, First Round Capital, Brightmind, Theory VC, Lockstep, Two Sigma Ventures, and a group of the cybersecurity industry’s most prominent operators.

Novee is the AI penetration testing platform built to secure an environment that’s constantly changing against attackers operating at machine speed. It starts with true black-box testing, reasoning about your environment the way a real attacker would: uncovering novel vulnerabilities, business logic flaws, and chained attack paths continuously, not just at fixed points in time. Built by veteran offensive security operators, Novee’s AI models are purpose-trained on real attacker tradecraft and adapt as your environment evolves, getting smarter over time. And because finding risk isn’t enough, every issue is validated and paired with precise, personalized fixes tailored to your architecture, tech stack, and business logic- so teams can reduce real risk as fast as attackers create it.

Opti is an AI-native identity security platform that transforms IAM for enterprises at scale. We turn complex identity decisions into precise, explainable, and instantly actionable insights, helping security teams enforce least-privilege access, reduce risk, and simplify compliance.

The Agentic infrastructure for the web - Automate any process performed on the web using AI agents that can use a browser just like a human does.

Dux is an agentic exposure management platform built for a world where vulnerability exploitation windows are collapsing from weeks to minutes. Use our AI agents to continuously determine what’s actually exploitable in your environment, identify the fastest path to protection, and eliminate exposure before it’s used against you. We bring exploitability, context, and action together - so you achieve safety at machine speed.

Managed security services, rebuilt for SecOps. Traditional MDR can’t keep up with modern threats. AI SOC tools help with investigations, but still require a SOC team. Daylight introduces Managed Agentic Security Services (MASS), a new model where AI agents and security experts run your security operations together.

imper.ai prevents AI-driven impersonation and social engineering by analyzing the device, network, and behavioral signals attackers can’t fake. Its real-time risk scoring and automated blocking verify every participant across voice, video, and chat before trust is established.

We’re working on something special. Trusted by world-class partners - 1011 and Brightmind Partners

Governance and risk management that starts from the change, not the questionnaire. What is Gist Security? Any meaningful change made by an organization, for example, a new feature, an infra update, an architecture decision, a new dependency or vendor,... can create risk that security and compliance teams need to review. Gist connects to where teams already work (Jira, GitHub, Cursor, Slack, PRDs), detects risky changes automatically, maps to policies and runs security and risk assessments in the background, feeding fixes to IT, dev and security teams inline. Plus, audit evidence is generated as a byproduct of the work - no questionnaires, no end-of-quarter audit scramble. Instead of starting from a framework and hunting for evidence after the fact, Gist starts from the change itself and ensures policies and controls are met as a byproduct of work. Security stops being the team that blocks progress and turns the review process into something that happens as you build. The business moves at AI speed while staying fully governed and defensible.
